Exactly six months after her husband's infamous cheating scandal surfaced, Liberty Ross has decided to call it quits on her marriage to Rupert Sanders.

The 34 year-old model's divorce petition was entered into Los Angeles County Superior Court on Friday (January 25) where she is asking for joint custody of the pair's two children, along with spousal support and that her attorney fees be paid by Sanders.

Leaving the family home in Los Angeles, Liberty Ross was swarmed by paparazzi as she headed to her attorney's office on Wednesday afternoon (August 8).

The aggrieved wife of adulterous director Rupert Sanders wore a white sleeveless top, fitted black skirt, black heeled boots and a black cross necklace. Absent from her hand, however, was her own wedding ring.
